Here's my question: in order to be a "slide" doesn't the lower body have to be on the dirt at least a little in front of the bag? Utley hit Tejada behind the bag before hitting the dirt at all. In my book that just isn't a slide. It's a hit.
Could I "slide" into first base by taking out the first baseman, hoping to disrupt a throw home to get a runner going from second to home knowing the "slide" play is on?
